It's really not that simple, since having exchanges around is always a good thing as more people are able to access bitcoin easily. With a bitcoin-friendly government it is probably a lot easier to spread the idea of bitcoin than with a bitcoin hostile government. This goes without saying ofc.
However as you said, bitcoin can indeed survive without China.
People will still trade in China, and still buy bitcoins. Tehy'll just do it another way. It's not like China is gone forever.
I don't know how they're government react when one of they're citizens will not follow them because I'm not aware of how they implement such policy.. But if it is forbidden to do so,, I will stop and never do that and wait for the change of heart of my government officials.. China might not be gone forever but I will not change my idea of a much better bitcoin community without them..
I agree to that mate.. Even japan alone can handle those investments because they have legalized bitcoin in that country.. China is just making noises to gain some attention.. Like a child play and china doesn’t really mature of how they think... It was not meant to regulate they want to own and be the center of the Blockchain technology and of the bitcoin community that is obviously impossible..
